The invention relates to a waste stock cover plate structure of a trimming and piercing die and a die of the waste stock cover plate structure. The waste stock cover plate structure comprises a lower die (2) and is characterized in that a waste stock cover plate (3) is arranged between the lower die (2) and a workbench (4) and used for preventing trimming and piercing waste stock from sliding into a T-shape groove and a push rod hole in the workbench (4); the waste stock cover plate (3) is arranged on the lower die (2); a lower die supporting rib (21) of the lower die (2) is provided with a mounting step (22); the waste stock cover plate (3) is arranged on the lower end plane of the mounting step (22) through fastening screws (1); and the plane where the ends of the fastening screws (1) are located is higher than the plane where the workbench (4) is located so as to ensure that the fastening screws and the workbench do not interfere with each other. The waste stock cover plate structure is simple in structure, low in cost, simple to manufacture and effective to operate, and can be used for preventing the trimming and piercing waste stock from sliding into the T-shape groove and push rod hole in the workbench.
Description
technical field [0001] The invention belongs to the field of molds, and in particular relates to a waste cover plate structure of a trimming and punching mold and a mold thereof. Background technique [0002] At present, the waste with a diagonal size less than 30mm in the trimming and punching die is handled by sliding out the waste slideway or receiving and storing the waste box. During the production process, due to the loosening of the waste slideway or the displacement of the waste box, the waste material falls into the T-shaped groove of the workbench or the hole of the ejector pin under the lower die, which brings inconvenience to the cleaning of the equipment workbench and affects the production efficiency. Contents of the invention [0003] The invention designs a waste material cover plate structure of trimming punching mold and its mold, which solves the problem of waste material falling into the T-shaped groove or ejector hole of the workbench under the lower m...
